So i got a pair of the OBX Long tubes racing headers with off road pipes instead of catalytics... A friend of me did the installation... We use etensions for the O2 sensors.. by the way I'm quite dissapointed with oshawa when we were taking if the 02 sensors the threading in two was just horrible like they put them wrong... We had to fix it with a file.

Anyways we did the install they sound great with the NPP and the AEM cold air intake.... Well after three Days I got a check engine light ..

My buddy has a Diablo tuberculosis so we connected to my car to read the codes and it gave us... " P015B" and " P015D" anyone know what they exactly mean ? And if I buy the new Diablo Sport intune if it will take it off ? Is it bad that im driving my 1LE with these codes ?

You can buy the inTune, but it won't solve your problem. You either need to get a custom tune from Ted Jannetty or a dyno tune.

^^ This ...When you put LT headers on you always throw codes until tuned. One thing you will get with the tune besides getting rid of the codes are maximum gains from your headers. Get it tuned and enjoy!
